The Unity Peacemaker Elite Barrel instantly upgrades the accuracy of your paintball gun. Unit Peacemaker Elite Barrel features precision machined and polished aluminum construction, with an internal diameter of .689 and a total length of 17 inches. The muzzle is threaded to accept most aftermarket tips and includes both an M16-style mock flash suppressor and an Apex-ready adapter as standard (Apex tip not included). The center of the Peacemaker Elite barrel features a raised ridge to prevent "shroud wobble" on US Army markers such as the Alpha Black Elite and Project Salvo.
